To stream 30gig mkv files with dts-hd or other hd audio. I want the best playback of audio and video to my system with the least amount of degradation

I tired a couple media tanks 5 years ago and they were difficult to set up with Gui setup.

Is there a tank that is plug and play with a nice interface with cover art and movie info. Similar to what xbmc or plex offers. Just point the box to network folder and it will scan and pull movie data down

NMJ is plug and play. You setup your pch to the share then hit red button and it will scan and collect media info itself, You can tweak it using NMJtoolbox from a windows pc. Plex app requires you setup a plex server again very minimal just basic install and point to media then launch plex app on the pch. Eversion/yamj is a very hands on requires a pc to update

there is zero transcoding. The only downside is if you use external subtitles you have to use a custom config file on the pch to tell it to use samba paths rather then plex http streams but its simple enough and still functions normally,

Also it does not support fling to. so you can load of plex on a tablet and tell it to play on the pch at this time you have to use the tv GUI to navigate
